* Great cities, like great wines, have to express their terroir. There is no one-size-fits-all model of urban success. Our cities are as diverse as their citizenry. To succeed, they need to express their own essential and unique character.

This is why you always have to be skeptical when somebody says something like "For Houston to be world class we have to do X like city Y." I believe that especially applies to heavy rail commuter transit in our decentralized, car-based city, but it also applies to recent questions like "Why can't Houston have downtown retail like Chicago's Magnificent Mile or New York's Fifth Avenue?" Because we're not like them, and we already have our pedestrian-oriented upscale shopping district: it's called The Galleria, one of the largest malls in the country, and with plenty of parking and climate control to boot!

* Don’t try to beat other cities at their game. Instead, make them beat you at yours. Cities are unique – yours included. Instead of fretting about measuring up to the planet’s elite metropoli or trying to emulate them, cities should figure out their unique strengths that other places can’t match.

Hear, hear! To quote an old post of mine: "Houston starts the 21st-century with a set of amenities 99% of the planet’s cities would kill for: a vibrant core with several hundred thousand jobs; a profitable and growing set of major industry clusters (Energy, the Texas Medical Center, the Port); the second-most Fortune 500 headquarters in the country (26); top-notch museums, festivals, theater, arts and cultural organizations; major league sports and stadiums; a revitalized downtown; astonishing affordability (especially housing); a culture of openness, friendliness, opportunity, and charity (reinforced by Katrina); global diversity; a young and growing population; progressiveness; entrepreneurial energy and optimism; efficient and business-friendly local government; regional unity; a smorgasbord of tasty and inexpensive international restaurants; and tremendous mobility infrastructure (including the freeway and transit networks, railroads, the port, and a set of truly world-class hub airports)."

* It says something powerful about a city when people vote with their feet to move there, to plant their flag, to seek their fortune. There is no more telling statistic about a place than in-migration. It’s important to know if people are moving into or out of a city–and why.

The most ignored statistic of the creative class city boosters, because their idols - NYC, Boston, Chicago, SF, LA - fail horribly on it.

* Moreover, new blood isn’t just nice to have, it’s essential. In an ever-more globalized, rapidly changing, competitive world, a city’s best interests are not served by being populated with people who’ve never lived anywhere else.

Points for our global diversity.

* But it isn’t just about the best and brightest, either. Attracting the educated is important, but cities are also where the poor come to become middle class, where immigrants come to build a better future for themselves and their families. Their needs must be taken up, too–and equally.

* A great city needs great suburbs. To pull our cities up, there’s no need to tear our suburbs down. To be successful in the modern era, its important for every part of a metropolitan region to thrive and bring its “A game”.

* “Building on assets” is a trap. The only reason we have any man-made assets in the first place is that previous generations of leaders didn’t follow that strategy. Only building on assets is a strategy about defending the past, not embracing the future. It is the spending down of our urban inheritance. Yes, leverage assets, but also add totally new things to the pot for future generations.

* We need to look forward, not backward. There is no more corrosive force than nostalgia. We should know where we’ve come from and what we stand for. But we can’t become imprisoned by a yearning for an imagined past that never really was.

* We need to embrace a 21st century vision of urbanism. Urbanism – Yes, but trying to copy Greenwich Village 1950 is not the answer. To find it, we must boldly re-imagine the possibilities of what a city can be and bravely identify what works today-and what doesn’t.

* We don’t know where this ride is taking us. We’re at a pivotal time in America’s urban history. So much is changing, and more change is yet to come. For our own sake, we should not assume that we’ve arrived where we’re headed, or that we have the answers. If there’s one thing we should take away from the urban planning failures of the past, it is a strong dose of humility.
